Commuters in Adelaide are in for a quieter, more comfortable ride as a newly converted hybrid train joins the green street fleet on the Adelaide Metro network.
After a successful testing period, the hybrid-diesel train will be servicing the Outer Harbor, Grange, and Belair lines, instantly recognisable by its distinctive bright-green wrap.
“In another milestone for a sustainable public transport future, the first of many hybrid-diesel trains will start taking passengers this morning,” Minister for Mining and Energy Minister for Transport and Infrastructure, Tom Koutsantonis says.

“Reducing our environmental impact and using significantly less fuel, this new hybrid-train also offers a great customer experience, particularly at Adelaide Railway Station where the diesel engine can remain off – reducing noise and fumes for those on board and in the station.”
“We are about exploring any technologies or solutions to de-carbonise and deliver a net zero-emissions public transport system.”
Hybrid-diesel trains represent a significant leap in eco-friendly technology, offering a quieter and cleaner alternative to traditional diesel trains. These green trains use up to 20% less fuel, reducing emissions and providing passengers with a more pleasant journey.

One of the key features of this hybrid train is the Energy Storage and Recovery System, which has been installed in each rail car of the two-car train set. These cars are just the beginning, with plans to outfit 44 diesel railcars with this innovative system.
The Energy Storage and Recovery System operates by capturing excess energy when the train brakes and storing it in a battery for later use.
This stored energy is also employed to power auxiliary loads, such as lighting and air-conditioning, at the train platform within Adelaide Railway Station. This not only reduces noise but also helps cut down on emissions and air pollution.
The installation of this energy-efficient system will be a phased roll-out, with all trains expected to feature the new technology by late 2024. Once fully implemented, Adelaide Metro anticipates saving an estimated 2,400 tonnes of CO2 emissions annually, contributing to a cleaner and greener city.
But the commitment to sustainability doesn’t end with the hybrid trains. Adelaide Metro is making strides towards a greener future for its entire fleet. Two hydrogen-powered buses hit the streets in late August, and the state’s first full battery electric bus is expected to start serving passengers by the end of October. These buses promise a smoother, quieter ride and a significant reduction in fuel-based pollution.
The move towards eco-friendly transportation aligns with the Government’s goal to transition the Adelaide Metro system into a zero-emissions public transport system, supporting the target of achieving net-zero emissions by 2050.
